Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Marinaded Mackerel
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash the mackerel and place them whole in a deep dish.
Add vinegar, water, salt, peppercorns, mustard seeds, cloves, bay leaves, shallots, sugar, butter, lemon slices, parsley, celery, crushed bell peppers, fennel, and sea kale.
Bake and serve
Cover the dish tightly and bake in a 350°F (175°C) oven for 1 hour.
Sprinkle baker's raspings over the fish and top with fresh lettuce leaves.
Re-cover the dish and serve when the lettuce is nicely cooked.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Forms the main body of the dish, cooking through gently in the marinade.
- Vinegar
- Provides acidity that flavours the fish and helps firm its flesh.
- Butter
- Adds fat that enriches the flavour and keeps the fish moist.
- Shallots
- Contribute a mild, sweet aromatic flavour to the marinade.
- Lemon
- Adds bright acidity and aroma to the marinade and fish.
The step that matters
Covering the dish tightly while baking. A tight cover traps steam so the fish cooks gently in the vinegar liquid. Without it, the liquid reduces and the flesh can dry out or cook unevenly.
Swap the clove
How well each one fits the dish's main ingredients (vinegar, mustard, shallot, sugar, butter, lemon, parsley):
- Capersfits better
- Tarragonfits better
- Thymefits better
- Clovethe original
Fit is the average pairing score against vinegar, mustard, shallot, sugar, butter, lemon, parsley. Candidates are from the same food group and used in at least 100 recipes.
